The greater Myrtle Beach area and Hilton head couldn't be much different. Not being a golfer, I found Hilton Head boring, with a shortage of restaurants and corresponding long lines and waits. The island seemed to shut down around 9. The entire coastline of Myrtle is prone to tropical storms.. here are a few links regarding pauley island in 2017:

Unlike the Villages you;re on the coast and you pay your money and take your chances. I spend at least one week in Myrtle during the summer at an ocean front condo. Any new structures have to be built on stilts to minimize flood damage, Property taxes are significantly less for permanent residents vs those that have second homes there ..
There are two bikers weeks that I know of.. one around memorial day .. not sure when the other is .. Given a choice, you don;t want to be there during them.. or certainly not near the section of town where many stay .. I've spoken to restaurant servers there .. They hate Biker weeks as the restaurants are filled but they claim the tips are horrendous .
There are folks I know that think the Villages is too far "north" to experience a nice warm winter... Do the math onhow much further north pauley;s or Myrtle is.. and look at the December to March temperature ranges to see if that fits your expectations and requirements ..
The ocean is great during the summer.. you probably can go in 4 .. maybe 5 months of the year
